I am trying to conceive My last period was the

Patient: I am trying to conceive. My last period was the 27th of january. I had some spotting on the 16th and 17th of february. I am now about 2 days late. I weaned down and also stopped taking zoloft per my dr 2 days ago. I had a bit of cramping, constipation and general fatigue for almost a week. All of my tests are negative. Today my breasts feel heavy and i have had some lightheadedness. What should I do?
